Beginning at the broad Columbia River and its companion interstate (I-84), SR 74 marks the beginning of the Blue Mountain Scenic Highway, which veers through arid, scrubby hills toward the distant Blue Mountains. Narrow tracts of green along the roadside typically indicate irrigated alfalfa fields. Windmill farms are another common sight as are grain elevators.
